sudo apt-get install dvdisaster How can I use it? As long as the circle fills up with "Green", is good but if there are a lot of "Red" sectors… it could mean trouble. And it's pretty impressive - but due to license Linus won't allow it in Linux (kernel - there is a fuse option for userspace). I like the "destructive testing" you did - it proves without a doubt that Btrfs does error correction.

Understand something, no one has ever asked this question that you have posed here because you are going about this wrongly....there is nothing to worry about using for instance dvdfab to Safecopy uses an incremental algorithm to identify the exact beginning and end of bad areas, allowing the user to trade minimum accesses to bad areas for thorough data resurrection. I understand that it makes at least 2 reads of the same chunck of data in order to verify that it provides the same read feed, if so, is considered as H_TeXMeX_H View Public Profile View LQ Blog View Review Entries View HCL Entries View LQ Wiki Contributions Find More Posts by H_TeXMeX_H View Blog 06-20-2010, 12:46 AM #6 russ00 LQ

Please re-enable javascript to access full functionality. The normal copy tools like cat, cp or dd do not allow creation of an image file from a disk or CD-ROM once reading of a sector failed. Dvdisaster also provides some routines that analyze the state of an optical medium. problem solved.

Because the volume of correction data increases in parallel with the number of reconstructable read errors, you can adjust the redundancy values to define whether a severely damaged image can still Why did Fudge and the Weasleys come to the Leaky Cauldron in the PoA? Using safecopys low level access features might help under some circumstances. Level is a bit field, add values together for more information: program flow: 1 IO control: 2 badblock marking: 4 seeking: 8 incremental mode: 16 exclude mode: 32 or for all

Parchive also made me remember the RAR archive format, particularly RAR3, which also adds redundancy to the archive, and allows the files to be reconstructed. A CDRW drive of the same age at work doesn't read any data from that part of the CD at all, while most DVD and combo drives have bad blocks every It will be attempted to retrieve more data from the listed blocks or from beyond the file size of the target file only.

Using smaller values for "-f" and allowing safecopy to backtrack for the end of the affected area "-r 1*". Poland: IDG Poland SA. For more DVD/Blu-ray digitizing tools and knowledge, visit my site at: http://dvd0101.com. Copyright 2012 CorvusCorax This is free software.

However, you do not need to recreate the error correction data every time you burn the ISO image; it can be reused for testing and for recovery purposes for later burning If -n is omitted the image will be expanded to the smallest possible medium size (CD, DVD, DVD9). Figure 3: Parameters for the error correction file are defined in the Error correction tab. Cdck measures the sector access times to give you an idea.

dvdisaster works exclusively at the image level. If you read data directly from a device there is no need to set this lower than the hardware blocksize. The operation sequence of safecopy has been kept relatively simple to assure this predictability. Generally when you rip a DVD it either rips correctly or it doesn't.

"You know what else I don't like? Maybe someone else will have some more clever ideas. ie wondering if they should be ripped like CDs, because to the best of my knowledge the disc will either be read correctly due to the error correction, or the ripping

Reliability: Data recovery from damaged media is a delicate task, in the worst case its success or failure can safe or ruin whole companies and seal affected peoples personal fate. Allowed values depend on the codec: RS01 error correction files -n x creates error correction file with x roots. -n x% creates error correction file with x percent redundancy. -n xm

Any part of the cluster can be recovered as long as the amount of damages in that cluster is smaller than the amount of added ECC data in that cluster, therefore more » Free Software Projects Although a couple of scratches are visible, you can read from the backup CD. Any or all of the above wrongly implemented could be screwing up your results. When I read the files back, it will automatically fetch multiple copies of the file, and give me the correct data - sort of like the way RAID works, but with

I'm assuming that you have a perfectly read-able optical disc (they say that it's okay even if it has few errors).

The type of a CD (Audio, Mode1, Mode2, etc...) is now successfully detected, and sector alignments are calculated correctly. We have to create an ISO image of the disc.
